“postinstall.rb:1in ‘require’ : no such file to load –
postinstall/set_environment (LoadError) from postinstall.rb:1”

I have no postinstall directory, should one have been corrected?

You have to make sure that the ruby\bin directory for the Ruby
included in Instant Rails is on your path before you run gem or
postinstall. The easiest way to ensure this is to open your Ruby
console window from Instant Rails using the menu item >>Rails
Applications>>Open Ruby Console Window"

I was following the instructions on the RMagick website, and did in fact
run the commands from the Instant Rails R. Console Window.

Given that the “gem install…” command appeared to work, presumably the
path to Ruby is functional.

Any more ideas? I can now find RMagick under the
Instant-Rails\Ruby\lib…\Gems\ directory, so it seems to have
installed itself there.
